RustCrypto-based provider implementation for version 0.23 of rustls, maintained by the RustCrypto organization.

Not only that this is incomplete that only few selected TLS suites implemented (it should be well enough to cover 70% of the usage), but the elephant in the room is that neither did rustls nor RustCrypto packages were formally verified and certified with FIPS compliance.

Note that RustCrypto performance is generally inferior than ring, but in exchange you got a pure Rust implementation that theoretically compiles everywhere Rust was ported to. In our case, we need to have std but foundational support for future no_std expansion is already here.
